[The nature of the primary interaction of saccharose from aqueous solutions with the oral cavity tissues].

The course of saccharose adsorption on surface tissues of the oral cavity directly after carbohydrate loading was studied in vivo. The amount of saccharose adsorbed on tissue surface was assessed from its desorption from an isolated site of the solid phase of the oral cavity and was correlated to a unit of tissue surface. Cariogenic potential in the oral cavity was shown to be maintained to a great measure at the expense of soft tissues and, specifically, of the glossal mucosa which is characterized by a high adsorption capacity for saccharose and represents a sort of a saccharose "depot" in the oral cavity. Carbohydrate adsorption appears to be a physical process. Water gargle after sugar intake fails to solve the problem of prevention of a cariogenic situation. Weakly acid gargling appears to be more promising desorbents of saccharose from oral tissues.
